Be it known that 1, JOHN a citizen of the United l the chains or S.RIenARDsoN, j chains pass over sprockets 14 on a shaft -15 States,residing in g carrier and, Nowesta, in the county olPembin-a and State,f sprockets 16 on a of North Dakota, have vinvented a new and p Theblades are thus uselul improvement 1n Buutile-LoadersJ oi secureduponthe chains or other carrying means so that as they are moved around thei per end oll the carrier. /llowen sprockets they project in a manner ll This invention relates to machines for picking up bundles or sheavesol grain from the ground and loading them onto wagons or racks moved atthe side of the machine; and its main object has been the simplificationof the construction oil the picking-up mechanprior application, Serial No. 184,295, -tiled by me on the 8th day of December, 1903.

The nature of my present improvements is fully disclosed, beov andillustrated in the l accomjianying drawings, forming a part of thisspecihcation, and 1n said drawings` Figure 1 is a partial plan showinglthe parts of the machine to which my invention relates. Fig. 2 is averticalse'ction on line 2 2 of Fig. 1. Fig. 3 is fa section on line 3 3of Fig. 1. Fig. elisa plan of the chains and blades, and Fig. 5 is asection on line 5 5 vof fie. 4.

which 'adapts them to enter underand lift the bundles lying in theirpath, and I find it desirable that they project from the chains in aforwardly-inclined direction of about forty degrees from the vertical,as seen at Fig. 3, and their outer edges are also beveled grecs Ato theplane of the blades, as also shown in said ligure, so that their forwardcorners are sharp and adapted to indent themselves into the bundles, andthereby efficient in taking hold and lifting them. The upper sprocketsmay receive power in the manner descibed in my previous application, andthe blades are employed in such number as may be necessary to enablethem to form a moving grating, through the openings ol which the bundlesafter they are raised from the ground cannot fall. l

At cach side the pick-up mechanism is lprol vided with a wind-board 1S,through whch l the sprocket-shafts pass and by y l lower one issupported, and the lower end is provided y with supporting-1-ollers 19,as

The machine of my present application is like that ol' my previous onein that it embodies an elevator or belt to which the bundles aredelivered by the pick-up mechanism and by which they are raised to theproper height for delivery This elevater is operated from thesupporting-wheels manner set forth in said application. The presentmachine is also propelled by, animal or other power, as set forth insaid application inasmuch as the changes now made in the machine are inthe pick-up mechanism, I have not thought it necessary to illustrate theother parts ot' the machine, with the exception of the elevator, aportion of the lower clearly shown. Above the wind-boards a verticalframework 20 may be employed to prevent the bundles from being thrownoff at the sides. l

The pick-up mechanism is attached to the side ofthe elevatorlOwithfreedom to rise and fallwith the uncvennc sscs 0i the ground, theshaft 17' serving es a pivot upon wlich it may rock; A portion or theweight of the forward end of the mechanism is taken from the rollers 19by means of spings 21 at each or receiving end cil which is shown at 10with side of the mechanism, such springs being its slats 11 and chain100. l mounted on rods 22, l'rcely joined to a sta- My improved picleupmechanism consists licnary bar 23, located below the shaft 17 of aninclined endless carrier ol' a width conand parallel thcrewithandsupported byhangsiderably exceeding the length of the bundles eis 24.The splines are conlined on the rods and havingl one end close to theground and l 22 between the collar 25, fast on the rod, and the otherelevated to a plane over that ol the I `the collar 2G, locse on the rod,and having a receiving end ol the elevator 10. This cnrl wing 27, bymeans oll which it is secured to rier consists of carrying means, suchas the l the adjacent wind-hoard. The spiings are parallel chains 12,prcl'erablv three in numl compressed and exert a lil`ting-p0wer 0n theber, and blades 13, secured edgewise upon l forward end o1l themechanism, preventing d riven shaft 17 at the up` backwardly at an angleof about thirty de' be rendered IOO great a depth'. A roller 28,extending from side to side of the piek-up. mechanism., is ar deliverthem to ranged at thehead of the latter and is adapted*V to draw thebundles from the g1 ating and the elevator 10. This roller is preferablydriven as shown at Fig. 1. The sides of the mechanism are alsesdesirablyprovided with shoes 29, adapted to ride upon the l ground.` The bladesare Ipreferably integral vfrom side to side of the mechanism and arebent up at tfieir centers, as seen at 33. so tl ey may not interferewith the sprockets oi" the central chain. i

In order to take up slack in the chains, the lower'shaft' has its endsreduced in dienl eter and threaded, and such enc1 s are passed throughelongated sloth 31 in ne tal pie cfs 30, attached to the shoes 29. Thenuts 32 cn the reduced ends clamp the shalt firmly in any desiredposition wit. in the lin its ol tlie slo'ts 31. Between thesprocket-wheels the sprocket-che ins 12 iide upen and are supper ted byangle-irons 34.

While I have shown the pick-up mechanism as suppoi ted at its l'oiwaidend both by caster-Wheels and shoes, it will be undei stood that theshoes do not noimally rf stupcn the ground, but ale employed to suppoi tt'ne pickup mechanism whrn the castel-wheels enter hollows 1n theground, and thereby to prevent.

.the mechanism from i'alling so liar as niglt result in its con' ing incontact w ith the ground or other obstructions. It will be noted thatthe caster-wheels are adapted to tuin er swivel in the devices by wi ichthey aie attached to the machine, and they may'also be attached atdifferent heigr ts, so es to regulate the height of the forward end oithe pickup mechanism, ii dcsiied.

I claim- 1,. In a bundle-loader, thel combination with an elevator forraising the bundles to the Wagon, of mechanism for picking the bundlesup from the ground and delivering them to said elevator, such mechanismconl sisting of an endless carrier moving over Wheelfat top and bottom,and having trans-I verse blades adapteil to lift the bundles onto theupper course of the carrier and to insure their transfer to saidelevator. l
